When I travel out of state for business I always love to travel by train. I am not a fan of having to take planes because let’s face it, it just gets way too cramped and half the time their heating and air conditioning does not work very well. On a train, or at least the ones I have been on the heating and air conditioning is really great just like a hotel. I always get a sleeper car if I am going a very long distance to make a mini vacation out of it. and always experiencing great heating and air conditioning on trains I can also say that the air quality has been really great too considering what you usually would expect from traveling by train. I always will pay the money to travel this way even if the company I work for is paying for airline tickets. I simply tell them how I feel about airplanes and will not travel on them. So yes, I have to pay extra money traveling this way. But it is all very worth it just to enjoy full indoor comfort from perfect air conditioning or heating along with the top notch air quality that I always receive on a train. I would never want to trade this in for anything in the whole wide world. However if there ever came a time where the heating and air conditioning stopped being good and the air quality got bad I would probably just travel by plane.
